“…A microstrip patch antenna with dodecagon (12 sided polygon) shape [10] was designed by introducing an irregular hexagonal slot on the patch, and circular polarization is generated at 2.45 GHz frequency. The DGS has been investigated and considered on the ground plane to reduce the size of the antenna and also increase the bandwidth [11].…”

Abstract-The design of a hexadecagon circular patch (HDCP) antenna for dual-band operation is presented in this paper. The proposed antenna operates at two resonating frequencies 13.67 GHz, 15.28 GHz with return loss of −42.18 dB, −38.39 dB, and gain 8.01 dBi, 6.01 dBi, respectively. Impedance bandwidths of 854 MHz (13.179-14.033 GHz) and 1140 MHz (14.584-15.724 GHz) are observed for the dual bands, respectively. To produce circular polarization, the HDCP antenna is incorporated with ring and square slots on the radiating patch. The defected ground structure (DGS) is considered for enhancement of gain. Axial ratio of the proposed antenna is less than 3 dB, and VSWR ≤ 2 for dual bands. The measured and simulated (HFSS, CST) results of the HDCP antenna are in agreement. The HDCP antenna can work at Ku band for satellite communications.

“…Further, the folding of the coupled line leads to a miniaturized power divider. The band width of the power divider is increased by using stubs [9] and defected ground structures (DGSs) [10,11]. The effect of open stubs on the power divider is discussed and its equivalent circuit is presented in [12].…”

“…Therefore the printed forms of that designs can be successfully exploited for ultra-wideband systems. Over the past years, several monopole antenna structures, such as rectangular [10], circular [11], elliptical [12], conical [13], tapered [14,15], slot-loaded [16][17][18] and defected ground [19][20][21][22] configurations, have been suggested for ultrawideband applications. The popularity of defected ground structure (DGS) in antenna study has increased immensely [19][20][21][22].…”

An ultra-wideband (UWB) monopole microstrip antenna is designed in this study. The design consists of a radiating triangular patch antenna (TPA) fed through a 50 Ohm microstrip transmission line (MTL) constructed over a defected ground structure (DGS). The triangular monopole well is matched to MTL with inserting a thin strip line. The performance of the proposed antenna is numerically investigated using method of moments (MoM) and verified through measurements. Based on the measured results, the antenna operates over large frequency range of 2.6-18.2 GHz at -10 dB. This makes the design suitable for UWB applications. The proposed antenna has better characteristics in terms of radiation pattern, peak gain and total efficiency across the operating ultra-wideband frequency range. Furthermore, the antenna system is suitable for near-millimetre wave applications, since the operating band reaches to 18.2 GHz.
